Here and in one other passage Paul uses the verb θριαμβεύω (thriambuo), to triumph. It is found but twice in the Bible, and only as descriptive of pentecostal grace, or, as in this text, of Christ's complete victory over all evil angels and spirits, even the highest in dignity and power. The cross was the Waterloo defeat of all malignant personalities. In what way? Let me explain. Love is power. The highest expression of love is the highest power. The cross is the highest manifestation of love possible in the universe. When Christ, the Son of God, voluntarily bowed his head in death, as a self-sacrifice for men, even for his enemies, he shook the empire of sin to its very foundations. His last cry on the cross, with a loud voice, was the shout of eternal triumph and victory. In a celebrated cathedral in Europe there is behind the altar a cross, with a ladder leaning against it, as if it had been just used in taking down the body of Christ. Beyond a hill in the background of the picture are seen the heads of four men who are bearing it reverently to the tomb. At the foot of the cross a stream of blood is running down the hill towards the spectator. In rapid flight from that crimson rill is seen a serpent instinctively hastening from his conqueror — the painter was a good theologian. But how does this victory of Christ help the Christian when hard pressed by the tempter? It gives great courage to continue the fight, when we are assured that we are battling with a vanquished foe, and that the victor is still in the field and within call, shouting to all his soldiers, "Be of good cheer, I have overcome the world." Faith makes his victory ours.
